[QUOTE="BudWalker, post: 8569, member: 787"] FLY069 is the flight where it appears there was an abrupt power loss. Unfortunately, the trick used in analyzing Mavic incidents of this type doesn't work for the Spark. That trick uses motorVolt data because it's faster (50 Hz) than the battery data (1Hz). Typically, the last few motorVolt data will show a drop of 50%. The .DAT for this incident doesn't show any significant drop in motorVolts at the end. There is a very slight drop due to the motors being commanded higher. Earlier in the flight there was a one sample drop to 9 volts on the rightBack motor. Kinda unusual.
